Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete block detection, and in particular to a performance detection device for concrete blocks. BACKGROUND

[0002] Concrete blocks are building components made of cement, aggregate and other materials through mixing, molding and curing, and are widely used in wall construction, foundation filling and other engineering fields. They have the characteristics of high strength, good durability, convenient construction and are one of the indispensable basic materials in the modern construction industry.

[0003] The performance of concrete blocks is directly related to the safety and stability of the building structure, and the extrusion resistance is a key indicator. If the strength is insufficient and the deformation resistance is poor, it may lead to serious consequences such as wall cracking and structure collapse. Therefore, performance detection of concrete blocks, mainly extrusion detection, is a key link to ensure the quality of construction projects and a hard requirement of industry standards.

[0004] The existing concrete block extrusion detection steps are to first place the block stably on the detection platform, apply pressure to one side or both sides of the block through the detection device, and observe and record the deformation of the block. After completing a group of detection, the block needs to be manually carried and turned over to change the placement angle, fixed after adjusting to the appropriate position, and then the next group of extrusion detection is performed. In this process, manual operation not only has high labor intensity and low efficiency, but also is prone to cause the block to fall and cause personal injury due to improper operation, and there is a risk of accidentally touching the start button of the equipment. Once the equipment is accidentally started, the extrusion structure will directly extrude the human body, which is extremely easy to cause injury and death accidents, and the accuracy of manual angle switching is difficult to guarantee, which also affects the reliability of the detection results.

[0005] Therefore, a performance detection device for concrete blocks is proposed. SUMMARY

Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0029] Please refer to Figures 1-6 The present application provides a technical solution:

[0031] Rotatably connected with rotary disc 8 on lifting platform 7, rotary disc 8 is arranged at the center position of lifting platform 7, connecting plate 2 is connected with connecting frame 13, connecting frame 13 is connected with fixed frame 18, one end of fixed frame 18 is rotatably connected with ratchet wheel 16, the lower surface of ratchet wheel 16 is connected with shaft, and the shaft is rotatably connected with one end of fixed frame 18, the upper end of ratchet wheel 16 is connected with limiting rod 17, the limiting rod 17 is provided with two, and the two limiting rods 17 are symmetrically connected on the ratchet wheel 16, the distance between the limiting rods 17 is matched with the width of the block, that is, the limiting rods 17 are clamped on the outside of the block after the block is placed, the through hole matched with the limiting rod 17 is formed in the rotary disc 8, since the rotary disc 8 does not rotate when separating from the limiting rod 17, when the rotary disc 8 falls, the through hole on the rotary disc 8 can be stably connected with the limiting rod 17, and the turning mechanism for driving the concrete block on the rotary disc 8 to rotate to change the detection direction is connected on the fixed frame 18.

[0032] Specifically, as shown in Figure 3 And Figure 4 The side of lifting platform 7 is connected with sliding clamp 14, the side of connecting plate 2 is connected with slide bar 5, and sliding clamp 14 is slidably connected on slide bar 5, and the stability of the structure of lifting platform 7 along slide bar 5 is improved by arranging sliding clamp 14.

[0033] Specifically, as shown in Figure 4 The lower end of lifting platform 7 is connected with arc block 15 matched with slide column 11, and the cooperation between slide column 11 and lifting platform 7 is stable by arranging arc block 15, so that lifting platform 7 is supported to rise in height.

[0034] Specifically, as shown in Figure 2As shown, the connecting plate 2 is connected with a deflection shaft 12, and one end of the cylinder 10 is rotatably connected to the deflection shaft 12. The deflection shaft 12 is vertically connected to one side of the connecting plate 2, and the fixed end of the cylinder 10 is rotatably connected to the deflection shaft 12. When the cylinder 10 is extended or retracted, one end of the cylinder 10 will rotate around the deflection shaft 12.

[0035] Specifically, as shown in the figure, Figure 5 As shown, the steering mechanism includes a translation frame 19, which is slidingly connected to the fixed frame 18. The translation frame 19 is rotatably connected with a ratchet bar 21. The ratchet bar 21 is connected with a spring 27 at one end, which can drive the ratchet bar 21 to deflect to one side of the ratchet wheel 16. The ratchet bar 21 is abutted on the outside of the ratchet wheel 16, and can drive the ratchet wheel 16 to rotate in one direction, thereby ensuring that the block can only rotate in one direction. The translation frame 19 is rotatably connected with a deflection block 20 through a hinged frame 22. When the translation frame 19 moves horizontally, the ratchet bar 21 will not be separated from the ratchet wheel 16, and the two structures are kept in abutting state. The structure of the deflection block 20 enables the slide column 11 to push the deflection block 20 to move horizontally without interfering with the resetting of the slide column 11 structure. The hinged frame 22 is connected with a spring 23. The spring 23 enables the deflection block 20 to abut on one side of the translation frame 19 under the condition of no external force. When the deflection block 20 is pushed by the slide column 11, the abutting side rotates and separates from the translation frame 19.

[0036] Specifically, as shown in the figure, Figure 5 The lower end of the translation frame 19 is connected with a sliding block 24, which is slidingly connected to the fixed frame 18. The sliding block 24 improves the stability of the translation frame 19 sliding along the fixed frame 18. The fixed frame 18 is provided with a sliding groove matched with the sliding block 24.

[0037] Specifically, as shown in the figure, Figure 3 and Figure 5 The fixed frame 18 is connected with a baffle 25 at one end, and the baffle 25 is connected with a slide rod 26. The baffle 25 can limit the resetting position of the translation frame 19. The structure of the translation frame 19 is reset by a spring 28. When the slide column 11 pushes the translation frame 19 to move along the fixed frame 18 towards the ratchet wheel 16, the spring 28 structure is compressed at this time. The translation frame 19 is slidingly connected to the slide rod 26. The translation frame 19 is connected with the spring 28 at one side, and the spring 28 is sleeved on the slide rod 26.

[0038] Specifically, as shown in the figure, Figure 5 The hinged frame 22 is connected to the translation frame 19 and the deflection block 20 away from the side of the ratchet wheel 16. The deflection block 20 is abutted on the translation frame 19 at one side.

[0039] To sum up, the performance detection equipment for concrete blocks provided by the embodiment, when the strength performance of the concrete block needs to be detected, the operator needs to place the block on the rotating disc 8. In the initial state, the limiting rod 17 is inserted into the rotating disc 8, and the limiting rod 17 can assist in positioning the placement of the block. When placing, the limiting rod 17 needs to be ensured to be as much as possible in the middle position of the two sides of the block. In the subsequent detection, the pressing plate 4 can push the block to the center position of the rotating disc 8. Therefore, through the auxiliary positioning of the limiting rod 17, the requirement for the placement of the block is low, and the operator can easily place the block.

[0040] After the block is placed, the air cylinder 10 is started, at this time the air cylinder 10 starts to contract, the air cylinder 10 is used to pull the slide column 11 to contact the arc block 15, so as to drive the lifting platform 7 to rise, at this time the limiting rod 17 is separated from the rotating disc 8, the lifting platform 7 rises, when the upper surface of the lifting platform 7 contacts the sensor 6, at this time the sensor 6 controls the detector 3 to operate, the air cylinder 10 stops contracting, the detector 3 can drive the pressing plate 4 to press the two sides of the block, when a certain pressure is applied, the operator can observe the state of the block, so as to understand that under the pressure condition, the block can meet the strength requirement, at this time the anti-extrusion performance detection of one side of the block is completed.

[0041] Subsequently, the pressing plate 4 moves away from the lifting platform 7, the air cylinder 10 starts to elongate, the lifting platform 7 descends, the limiting rod 17 is inserted into the rotating disc 8 again, as the air cylinder 10 continues to elongate, at this time the slide column 11 starts to move along the horizontal direction, until the slide column 11 contacts the deflection block 20, the slide column 11 continues to move, the deflection block 20 is deflected under the drive of the slide column 11, at this time the translation frame 19 abuts against the baffle 25, when the slide column 11 drives the deflection block 20 to move away from the deflection block 20, the air cylinder 10 is elongated to the maximum state.

[0042] Subsequently, the air cylinder 10 starts to contract, at this time the slide column 11 connected to the telescopic end of the air cylinder 10 moves horizontally to contact the deflection block 20, so as to drive the deflection block 20 to move horizontally, at this time the deflection block 20 moves synchronously with the translation frame 19, the spring three 28 structure is compressed, at this time the ratchet bar 21 can drive the ratchet wheel 16 to rotate, the ratchet bar 21 is deflected to the direction of the ratchet wheel 16 under the action of the spring two 27, the rotation of the ratchet wheel 16 can drive the rotating disc 8 to rotate through the limiting rod 17, when the slide column 11 enters the vertical part of the L-shaped slot 9, at this time the slide column 11 is separated from the deflection block 20, at this time the translation frame 19 connected to one side of the deflection block 20 is reset under the action of the spring three 28, until the translation frame 19 abuts against the baffle 25 on one side, because the structure of the ratchet bar 21 makes it not rotate the ratchet wheel 16 when resetting.

[0043] When the slide column 11 is separated from the deflection block 20, the ratchet wheel 16 completes a 90-degree rotation, at this time the air cylinder 10 continues to contract, so that the sensor 6 can be pressed down, at this time the pressing plate 4 can perform anti-extrusion test on the other pair of vertical side surfaces of the block, after the test is completed, the air cylinder 10 is elongated until the slide column 11 connected to one end of the air cylinder 10 moves to the lowest point of the vertical height, at this time the air cylinder 10 stops running, the limiting rod 17 is reconnected with the rotating disc 8, at this time the performance detection work of a single block is completed.

[0044] The device realizes automatic rotation of the block after placement to change the extrusion angle, without manual intervention in carrying and overturning the block, which fundamentally avoids the situation that the block may fall and injure people during manual operation, greatly improves the safety of the detection process, and accurately controls the rotation angle of the block through the mechanical structure, ensures the consistency and accuracy of each angle switching, avoids the angle deviation caused by manual operation, makes the detection result more reliable and comparable, and provides a strong guarantee for accurately evaluating the anti-extrusion performance of the concrete block.

Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
